Neutrik NC3FX-B 3-Pin Female XLR Cable Connector Gold

The Neutrik NC3FX-B is a 3-pin female cable-mount XLR connector — the termination you solder onto the source end of a balanced microphone or line-level cable. Its gold-plated contacts are the key specification: gold resists oxidation where nickel or copper eventually develops a resistive layer, and in a balanced mic circuit where you're working with signals as low as -60 dBu, consistent contact resistance is the difference between a clean noise floor and intermittent artifacts that cost time to troubleshoot. The screwless 4-part design is a Neutrik hallmark — the housing assembles cleanly without additional hardware, and the chuck provides reliable cable strain relief when properly torqued. Manufactured in Liechtenstein to controlled tolerances, the connector holds its pin geometry and mating force specifications across thousands of connection cycles.

This connector is the standard choice for professional audio technicians building or rebuilding microphone cables, patch bay wiring, balanced insert loops, and stage snake terminations. It mates with any compliant 3-pin male XLR (stage boxes, preamp inputs, mixing console XLR jacks) and handles both mic-level and line-level balanced signals without modification. For a touring engineer who builds their own cables, the NC3FX-B is the repair kit staple — reliable enough that it's never the suspect when you're chasing an intermittent signal problem. For studio builders wiring a patchbay or loom, it's the connector that won't introduce a noise floor variable. It is, simply, the industry-standard female XLR connector, and it earns that status with consistent, verifiable quality.
